I think it's wonderful when someone explores science principles in something in our everyday world and there is an interesting article (with some math I'm not advanced enough to do more than poke at) in the latest issue of Physics Today:

Page is a leading expert on the use of multiply scattered acoustic waves to study changes in physical systems and the movement of particles through a medium, in this case bubbles in a glass of beer. He directs the university’s ultrasonics research laboratory, one of only a handful in North America focused on this technique.
It's a good read and not all of it is math!
It is a good read...! I was surprised to find that I grasped a lot of it (fresh from a physics course this past Spring, of course).
Actually, fluid dynamics is apparently something that is not really well understood, even by the experts (according to my physics professor). So no one should worry!
